It has been the practice in this art to wheel the edges of boots and shoes before they are inked, and frequently before they are trimmed, and in order that they may present a clean, bright, and uniform appearance it is desirable to go over them with a brush or hand-wheel after the inking has been done. The present invention makes this hand-hm ishing unnecessary and greatly improves the quality of the work.

Novel and advantageous features of a machine made in accordance with my invention include a burnishing-tool having a roLnded outer edge, the same being adapted to be re ciprocated in the stitch indentations and the purpose of the rounded ends being to prevent any tendency of the tool to scrape and rotghen the stitch impressions, means for maintaining the tool in contact with the indentations during its reciprocation, an adjustable work-support operatively related to the tool, means for adjusting the tool relative to the work-support, and means for throwing the tool into or out of operative engagement with its actuating means. More i specifically, the burnishing-tool is composed I the preceding figure. Fig. 5 is a bottom view of the work-support shown in Fig. 1. Figs. 6 and 7 are details of the tool, and Fig. 8 is a detail of the cam and plunger roller.

Referring more speci'lically to the drawings, wherein like reference characters refer to corresponding parts in the several views, A designates the frame of the machine, which is provided with two bosses a a and lugs or projections a, a", and of. The bosses are iitted with bushings A A, in which is journaled a shaft E.

B is a hollow cylindrical case, from the ends I) of which project bearings i) b", which are bored to receive the bushings before referred to, about which the case is free to pivot. This case is also provided with a projection b", the purpose or which will be hereinafter described.

The shaft E is journaled in the bearings or bushings A A, and endwise movement thereoi is prevented by a hub f of a pulley F, bearing against the end of the bearing b at one end, and the collar G, bearing against the end of the bushing A at the other. The collar G is secured to the shaft by means of a set-screw 9. At a point about midway between the faces b of the casing B the shaft E is milled to form flat faces or cams e, four of these being shown, but any desired nummachine or in a plane transverse to that of her being provided in different machines according to their use. The function of these cams will hereinafter appear.

The projection l) projects radially from the cylindrical case B and is bored to receive a plunger ll, said plunger being of a reduced diameter at its forward end and fitted to slide freely through a bushing l, threaded into the projection b. The opposite or rear end h of the plunger If is turned to fit the bore of the projection b, and its end is slotted to receive a roller J, the latter being journaled in the plunger H through' the medium of a pin Resting against the shoulder formed by the enlarged or rear end Ii of the plunger and encircling the reduced forward portion thereof is a coiled spring K, the other end of the spring resting against the end of the bushing I. The purpose of the spring is to hold the plunger H in a retracted position and force the roller J against the cam-faces of the shaft E.

On the outer end of the plunger H, I provide a burnishing-tool I), which is free to revolve about a pivot (I and is prevented from slipping therefrom by a screw (i The burnishing-tool is tapered, being preferably frusto-conical; but its axis (Z is at an angle to the longitudinal axis of the plunger, whereby the lower or working portion of the burnishing-tool is substantially parallel to said longitudinal axis of the plunger. The burnishingtool, while free to progress in a rotary direction to present a working surface to each of the stitch impressions or indentations surrounding the sole of the shoe, is simultaneously rapidly reciprocated to burnish said impressions or indentations through the medium of the rotating cams c on the shaft E engaging the roller J on the plunger and forcing the same outwardly in opposition to the quick return motion thereof under the influence of the spring K. Owing to the reciprocating movement imparted to the burnishingtool it is quite essential that the ends of the flutes on the tool be heveled or rounded in all directions at the outer ends there of to prevent the otherwise sharp edges of the tool from scraping or roughening the impressions attending the present invention, and possibly would not be necessary in machines where the tool is not reciprocated while in'engagement with the stitch impressions. In its back-and-forth movement the plunger H is prevented from turning by reason of the side faces of the cam engaging roller J being con fined between the inner ends of the bushings A A The shaft E is rotated through the medium of a belt-pulley F at one end thereof, power bein transmitted to said pulley from any suita le source, and it is of course desirable that instrumentalities be afforded whereby the actuation of the burnishing-tool may be This is an important feature,

stopped without interfering with the continuous operation of the shalt. To this end a portion of the bush A overlaps the cam portion of the shaft l), the other portion of said bush being cut away to permit the contact of the cam-roller J with the faces of the cams. .lt obvious that by rotating the bushing A about the shaft the overlapping portion a thereof will act as a cam, and, riding under the roller J, will force said roller away from contact with the cam portion of the shaft, and so stop the motion of the plunger H normally incident to the rotation of said shaft, Fig. 8. The turning of the. bushing A in order to stop the movement of the plunger, as just defined, is conveniently cf fected by means of an operating-handle S, threaded into a cap it, covering the end of the shaft E and collar G and fitted to the bushing A Ihe inner end of this handle fits into a complementary hole in the bushing, and owing to this connection when the handle is manipulated said bushing is turned about the shaft E and the cannroller J allowed to come in contact with the cam portion of said shaft or pushed away from engagcment therewith, according to the desire to start or stop the reciprocation of the plunger. Two pins b projecting from the face of the casing B, limit the moven'ient of the handle S in opposite directions.

A spring L tends to hold the casing B down. against the head of an adjusting-screw M, threaded into the lug a of the frame A, the tension of said spring being adjusted by a thumb-nut N and cyobolt O, to which the spring is attached. It is also by means of this spring that the burnishing-lool is kept in contact with the stitch impressions or indentations while being rapidly rcriproratei'l therein. A portion of the case B is tut away, as at b, so that the casing B will set over and span the bearings a a of the frame A, the opening provided by the cut-away portion being sullitient to permit the moyenient of the casing B about the bushings on which it is journaled.

A table-supporting rod 1 is firmly secured in the lug a of the frame A, which is bored. to receive it. The outer end of this rod is approximately rectangular in cross-section, and the table (represented at C) is prox idcd with two depending lugs 0 adapted to span said rectangular end of the rod, whereby the table may be pivoted thereto by means of a pin 0. To look the table in adjusted positions relative to the burnishing-tool, the end of the rod P is slotted from its outer end inwardly and is provided with a screw Q, threaded through one half of said slotted end and hearing freely against the inner face of the opposite half thereof. Owing to this arrangement the turning of the screw Q inwardly causes the two members of the slotted rod to separate or expand between the two lugs c on the table, whereby the adjoining surfaces of said members and lugs Wlil impinge with suiiicient force to frictionally resist accidental displacement of the work support or table. This adjustable table feature of the invention will not be claimed herein, inasmuch as it more properly constitutes subject-matter for a divisional ap lication.

A treadle-ro T, engaging a pin 1) on the casing B, provides a means for rotating the casing against the action of the spring L and elevate the burnishing-tool to permit the insertion and withdrawal of the work from between the tool and the work-supporting table. The lower end of the treadle-rod is connected with any suitable iloor-treadle.

The burnishing-wheel may be heated by gas or other means, a tubular portion 1) being cast on the case B for C011V61'll81168 in attaching gas appliances.

The operation of the machine may be described as follows: After heating the burnishing-tool and adjusting the same relative to the table by means of the screw M and setting the table at the desired angle to said tool, the shaft E being revolved through the medium of its pulley, the handle S is manipulated, so as to allow the roller J to contact with the cam portions of the shaft. This immediately imparts a high reciprocating movement to the plunger H and burnishingtool. The burnishing-tool is then raised away from the table by means of the treadle to permit the insertion of the work therebetween. Thereafter the treadle being released, the spring L holds the burnishingtool in constant engagement with the work and maintains the work 11 ion the table. The pitch and ribs of the too correspond to the stitch impressions or indentations reviously made in the edge of the sole, ant by drawing the sole edge under the rapidlyreciprocating burnishing-tool, the movement of the tool being in line with the direction of the impressions, it cleans and burnishes each impression and gives them avery superior finish. The free rotary movement of the tool permits the same to act progress ively from stitch to stitch without disengaging the same from the work or in the least impeding its reciprocatory movement as the shoe-sole is passed therebeneath.

I am not unmindful of the fact that in some instances the present machine may be employed with slight or no change for both forming the stitch impressions or indentations an'd burnishing or finishing the same.

In these specifications where I have employed the term wiping as defining the action of the hurnisl'ling-tool l have so employed the term more particularly with a view of distinguishing the action from the in-and-out movement of an indenting-tool or indenter.
